Long-Term Outcomes Following Transarterial Embolisation of Proximal Type I Endoleaks Post-EVAR.

Purpose: To describe the long-term outcomes following transarterial embolisation for type Ia endoleaks (ELIa) in patients who failed or were unsuitable for standard endovascular/surgical options.

Materials And Methods: A retrospective single-centre observational study was performed between October 2010 and April 2018. Technical success rates and long-term outcomes were evaluated.

Outcome of endovascular treatment of internal iliac artery aneurysms: a single center retrospective review.

Purpose: To evaluate the technical feasibility and clinical outcomes of endovascular treatment for internal iliac artery (IIA) aneurysms.

Material And Methods: This was a retrospective analysis of 25 patients with 32 IIA aneurysms (mean diameter: 39.1 ± 12.

Randomised Controlled Trial of Particles Used in Uterine fibRoid Embolisation (PURE): Non-Spherical Polyvinyl Alcohol Versus Calibrated Microspheres.

Purpose: The PURE study is a randomised controlled trial (RCT) comparing the clinical and MRI outcomes of patients treated with non-spherical polyvinyl alcohol, ns-PVA (Contour PVA-Boston Scientific-355-500 & 500-700 microns) versus calibrated hydrogel microspheres (Embozene-Varian Inc-700 & 900 microns) for symptomatic uterine fibroids.

Materials And Methods: Prospective, ethically approved non-sponsored RCT in 84 patients in a single UK tertiary IR unit, ISRCTN registry trial number ISRCTN18191539 in 2013 and 2014. All patients with symptomatic fibroid disease were eligible.

Secondary Endoleak Management Following TEVAR and EVAR.

Endovascular abdominal and thoracic aortic aneurysm repair and are widely used to treat increasingly complex aneurysms. Secondary endoleaks, defined as those detected more than 30 days after the procedure and after previous negative imaging, remain a challenge for aortic specialists, conferring a need for long-term surveillance and reintervention. Endoleaks are classified on the basis of their anatomic site and aetiology.

Predicting the Fibroid-Migratory Impact of UAE: Role of Pre-embolization MRI Characteristics.

Aim: To investigate potential factors on MR imaging that could be used to predict migration of uterine fibroids post-UAE.

Methods And Materials: We retrospectively reviewed patients referred for UAE having pre-procedural and 6 months post-procedural MRI, at a tertiary centre, over a 1-year period. Pre- and post-UAE images were reviewed in 64 women by two radiologists to identify the sub-type, dimensions, and infarction rate of each dominant fibroid.

Secondary interventions after endovascular aneurysm sac sealing: endoleak embolization and limb-related interventions.

The Nellix endovascular aneurysm sealing system is a novel alternative to conventional endovascular aneurysm repair for aortic aneurysm management using paired balloon expandable endografts supported by polymer-filled endobags to achieve sealing and anatomic fixation. Part of the promise of endovascular aneurysm sealing is increased resistance to lateral and longitudinal forces and thus a potential for reduced rates of device-related failures, particularly endoleaks. Initial efficacy data on this device are encouraging, but our knowledge of its associated complications and their management is limited.

CT of Normal Developmental and Variant Anatomy of the Pediatric Skull: Distinguishing Trauma from Normality.

The use of computed tomography (CT) in clinical practice has been increasing rapidly, with the number of CT examinations performed in adults and children rising by 10% per year in England. Because the radiology community strives to reduce the radiation dose associated with pediatric examinations, external factors, including guidelines for pediatric head injury, are raising expectations for use of cranial CT in the pediatric population. Thus, radiologists are increasingly likely to encounter pediatric head CT examinations in daily practice.

Transarterial catheter embolisation for an unusual cause of upper gastrointestinal haemorrhage.

A 72-year-old man with a history of gallstones, and complex cardiac and endocrinological comorbidities, presented with severe abdominal pain and melaena. CT mesenteric angiogram showed a cystic artery pseudoaneurysm and gallbladder distended by haematoma. Subsequent mesenteric angiography confirmed a cystic artery pseudoaneurysm, which was successfully embolised with microcoils.

Thoracic Endovascular Aortic Repair for the Treatment of Aortic Dissection: Post-operative Imaging, Complications and Secondary Interventions.

Thoracic endovascular aortic repair (TEVAR) has become an accepted alternative to surgery for the treatment of aortic dissection (AD). Lifelong surveillance is obligatory following TEVAR to monitor the aortic morphology and detect associated complications. This is particularly important in AD where coverage of the primary intimal tear is necessary in achieving thrombosis and regression of the false lumen.

Dual-energy CT for imaging of pulmonary hypertension: challenges and opportunities.

Computed tomography (CT) is routinely used in the evaluation of patients with pulmonary hypertension (PH) to assess vascular anatomy and parenchymal morphology. The introduction of dual-energy CT (DECT) enables additional qualitative and quantitative insights into pulmonary hemodynamics and the extent and variability of parenchymal enhancement. Lung perfusion assessed at pulmonary blood volume imaging correlates well with findings at scintigraphy, and pulmonary blood volume defects seen in pulmonary embolism studies infer occlusive disease with increased risk of right heart dysfunction.

Dual-energy computed tomography in the assessment of vascular and parenchymal enhancement in suspected pulmonary hypertension.

Purpose: To evaluate quantitative differences in central pulmonary artery (PA) and pulmonary global and regional enhancement in patients with and without pulmonary hypertension (PH) using dual-energy computed tomography (DECT).

Materials And Methods: We retrospectively studied 391 thoracic DECT studies and identified 89 patients with PA pressure (PAP) data and a pulmonary angiogram. PH was defined as a mean PAP of ≥25 mm Hg on right heart catheterization (RHC) (n=19) or a systolic PAP of ≥40 mm Hg on echocardiography (n=20).
